 We have multiple WordPress sites we maintain and when updating plugins
 today we keep gettings Server error 500 instead the normal maintenance
 message. Error logs show same PHP Fatal error in all instances.

 PHP Fatal error. Uncaught Error: Call to undefined function
 trailingslashit() in /data/wordpress/wp-includes/class-wp-textdomain-
 registry.php:103

 Hope you can fix this bug soon. Thank you!

 Kind regards,
 Mika Suhonen
